Nice Roberto, Very nice,
I propose we use this instead of what we have. Please look at it and
comment.
1. Audio content does not contain background sounds OR the background
sounds are at least 20 decibels lower than the foreground audio content with
the exception of occasional sound effects. </proposed>
ALSO - I think that we should combine this one (which only has one - level 3
success criteria) with the previous guideline. So think about this too.

I agree
Any wordsmiths that can figure out how?

Subject: R: Is the word Short measurable
The problem is that we should be able to creare a SC so that no
particular
kind of media is left out.
I think we should find the way not to specify fixed numbers, but I
realize
it's almost impossible if we want to keep the SC testable; also the 20
db
threshold is a fixed number, but in that particular case, I feel that
it's a
reasonable compromise.
Best regards,
Roberto Castaldo

Better
But I think this would still eliminate all war films.
It is level 3 but…
I wonder if we can figure a way to get what we want without catching so
much
else that it would be ok to leave out.

I propose we rewrite:
Level 3 Success Criteria for Guideline 1.5
<current>
1. Audio content does not contain background sounds OR the
background
sounds are at least 20 decibels lower than the foreground audio content
with
the exception of occasional short sounds. [V] </current>
<proposed>
1. Audio content does not contain background sounds OR the
background
sounds are at least 20 decibels lower than the foreground audio content
with
the exception of occasional short sounds. (where “short” may be defined
as
less that 10 seconds and “occasional” may be defined as occurring more
frequently than once every 10 minutes.) [V] </proposed>
In an attempt to make our guidelines testable, I chose 10 seconds as the
as
the threshold for the word “short” to allow for what the movie industry
would describe as an airplane passing overhead or a bomb exploding. I
chose
10 minutes as the threshold for “occasional” because I think any more
frequency than that would be quite distracting and difficult to follow
